404b is a bookmarklet that attempts to request all links on a given page to verify that they load correctly. It uses document.links to obtain the list of links on a page and either issues a XMLHttpRequest for same domain links or creates a link element to verify that the link works. This bookmarklet is tested on Chrome only right now.
Create a new bookmark (cmd+d or ctrl+d) and replace the URL with the following code:
javascript:(function(){s=document.createElement('script');s.type='text/javascript';s.src='https://raw.github.com/emecell/404b.js/master/dist/404b.min.js?v='+parseInt(Math.random()*99999999);document.body.appendChild(s);})();
Initial design is based off of the WTFramework bookmarklet.
